Overview
lmcache is an A LLM serving engine extension to reduce TTFT and increase throughput, especially under long-context scenarios.
Affected versions of this package are vulnerable to Use of Weak Hash in the hex_hash_to_int16 function of the KV Cache Handler process. An attacker can compromise data integrity or cause partial denial of service by exploiting the use of a weak hash algorithm through local access with low privileges and high attack complexity.
